Passing props between React components is fundamental for creating reusable, modular components and establishing proper data flow in component hierarchies. As the creator of CoreUI, a widely used open-source UI library, I’ve designed thousands of React components that rely on props for customization, data sharing, and flexible API design in enterprise applications. From my expertise, the most effective approach is to pass props as attributes to child components and destructure them in the function parameters. This method provides clean component interfaces, type safety with TypeScript, and excellent developer experience with IntelliSense support.
